Title: Dummy bar head for continuous casting of broad thin slab
Inventor: KANAZAWA TAKASHI
IPC: B22D11/08
Filed: 1994-10-17
Abstract: PURPOSE: To improve the yield at the time of starting casting in highspeed continuous casting of a broad thin slab by using a dummy bar head which is formed to a V-channel shape in section and has projecting parts in the groove. CONSTITUTION: The dummy bar head 10 for continuous casting of the broad thin slab is formed to the V-channel shape in section and is provided with the many projections 16 on the inside surfaces of side walls 14, 14 constituting the groove part 12. This dummy bar head 10 is connected to a dummy bar and is inserted into a casting mold 22. Molten metal is poured therein and continuous casting is started. The funnel-shaped dummy bar head 10 having the V shape in section is formed, by which the completely solidified part of the slab part in the initial period of casting is lessened. The direct contact of the casting mold 22 with the dummy bar is lessened and the cooling from the casting mold 22 is lessened as far as possible if the thickness of the dummy bar head 10 is gradually reduced in a casting direction. While the solidification of the dummy bar and the slab is assured, the subsequent solidifying is suppressed and the unsolidified layer is made to remain as far as possible.

Abstract: PURPOSE:To equalize the stress by providing a load supporting part in the lateral direction and in the torsional direction of the load to be applied to a leaf spring on each end part in the lateral direction of each rigid member which is fixed in an alternate manner with an elastic body to form a plate-shaped spring body to provide sufficient supporting function. CONSTITUTION:Lip parts 22 of approximately semi-disc shape are provided in a projecting manner in the longitudinal direction on each end part in the lateral direction of one end surface 21 of rigid members 2 constituting a plate-shaped spring body by alternately fixing the rigid members 2 to an elastic body 3. One end surface 21 is made flat, and the end surface 23 on the opposite side is formed in the recessed shape whose section is of approximately semi-circular shape, and the elastic body 3 is made of approximately semi-cylindrical body, and the flat surface part 3a and the respective end surfaces 3b are adhered to one end surface 21 of one of the rigid members 2, and the inner surface 22a of the lip part 22. In addition, the projecting surface 3c of the elastic body 3 is adhered to the other end surface 23 of the other rigid member 2 to be fixed to each other, and the load in the width direction or in the torsional direction is applied to the outer circumferential surface 22b of the tip part 22 of one of the rigid members 2 and the other end surface 23 of the other rigid member 2. Thus, the sufficient supporting function is realized and the stresses exerted on the leaf spring can be unified.

Title: Inverter
Inventor: ASAEDA TAKEAKI
IPC: H02M7/48
Filed: 1989-09-27
Abstract: PURPOSE:To prevent lowering of regeneration efficiency by bypassing the current flowing through a regeneration current transformer, arranged between snubber circuits in positive and negative arms of an inverter, when the load current is lower than a predetermined level. CONSTITUTION:Snubber circuits 4U, 4X are connected in parallel with positive and negative arms 1U, 1X connected in series across a DC power supply PN. A gate turn off thyristor GTO 5 is connected in series with the primary winding 6a of a regeneration current transformer 6 connected between the joints of a capacitor 41U and a diode 42U, and a capacitor 41X and a diode 42X constituting the snubber circuits while a GTO 8 is connected in parallel therewith. When a GTO 1U is turned OFF under a condition where the load current is lower than a predetermined level, GTOs 5 and 8 are turned ON simultaneously and the primary winding 6a is bypassed thus ensuring the simultaneous OFF time. Upon elapse of the simultaneous OFF time, GTO 8 is turned OFF simultaneously with turn ON of GTO 1U. By such arrangement, magnetic saturation of a transformer 6 is prevented resulting in prevention of lowering of regeneration efficiency.

Title: Polishing apparatus
Inventor: TANAKA KOICHI
IPC: B24B37/04
Filed: 1988-10-06
Abstract: PURPOSE:To realize a high-flatness polishing operation of a semiconductor sheet by a method wherein a plate where a flat object to be polished has been fixed to the rear-surface side and a head part surrounding the circumference of the plate are separated via a gap part. CONSTITUTION:A plate 11 is connected to a head part 12 via a holding means 14 whose position is regulated in a direction of a gliding movement face of an object 3 to be polished. That it to say, a part between an outer peripheral wall of the plate 11 and an inner peripheral wall of the head part 12 are connected by using the ring- shaped non-elastic and flexible thin-layer object 14; a circular space 15 is sealed airtightly. A mounting position 14a on the outer-surface side of the freely gliding plate 11 is set at a part which is lower than a mounting position 14b on the inner- surface side of the head part 12; a vertex P formed on a virtual extension line of the holding means 14 is constituted so as to coincide with a polishing face 1A of a semiconductor sheet 3. Thereby, when a polishing operation is executed, a retention force cancelling a force S from polishing cloth by a polishing resistance generated between the sheet 3 and the polishing face 1A cancels an action force because the vertex P of a virtual cone is situated on the polishing face 1A; the plate 11 is not tilted forward. Thereby, a high parallelism can be maintained.

Title: Temperature controller for electric heater
Inventor: KATAYAMA HISAYASU
IPC: G05D23/19
Filed: 1985-11-08
Abstract: PURPOSE:To prevent such a case where the temperature of a heating element rises up limitlessly by avoiding the change of the setting voltage of the temperature of a heating element regardless of the resistance value of a variable resistor for the signal of a thermistor when the room temperature is lower than a set level. CONSTITUTION:When the room temperature is less than a set level, the resistance value of a thermistor 36 is increased. Then the room temperature signal voltage VT is less than the room temperature set voltage VS and the forward voltage is applied to a diode 35. Here the resistance levels of the 1st and 2nd resistances 33 and 34 are set considerably lower than the synthetic resistance level of the thermistor 36, the 3rd resistance 37, the 4th resistance 39 and variable resistors 40 and 41. As a result, the voltage VT is equal to a level obtained by subtracting the forward drop voltage of the diode 35 from the voltage VS. Then the base voltage of a transistor 38 has no change despite the change of the resistance level of the thermistor 36. Thus the temperature setting voltage VH of the heating element has no change either. As a result, the temperature of a heating element 2 has no change and is kept constant.

Abstract: PURPOSE:To prevent the peroxidation of treating material during combustion of soot by heat treating the treating material in a gaseous atmosphere of a correct carbon potential and reducing the pressure in a furnace in a temp. range in which soot burns without decarbonization, then restoring the pressure by air. CONSTITUTION:The treating material 7 in a cooled shape or the like is charged into a heat treating chamber 2 and is heated by a heater 4. The carbon potential of the gaseous atmosphere in the heat treating chamber 2 is controlled to prevent the decarburization of the treating material 7. The material 7 is slowly cooled and is transferred into a burnout chamber 3 when the material 7 attains a prescribed temp. The temp. range where the material 7 is not decarburized and the soot burns is maintained in the burnout chamber 3 and the inside in the chamber 3 is evacuated to a reduced pressure. A valve 6a is opened to restore the pressure by air. The soot sticking to the surface of the material 7 is burned by the infiltration of the air. The peroxidation at the surface layer part of the treating material during the combustion of the soot is prevented and the pickling of the post stage is simplified.
